portCfgNonDfe
Enables or disables non-Decision Feedback Equalization (DFE) mode on 8 Gbps Fibre Channel links.
SYNOPSIS
portcfgnondfe --enable [slot/]port[-port]
portcfgnondfe --disable [slot/]port[-port]
portcfgnondfe --show [slot/]port[-port]
portcfgnondfe --help
DESCRIPTION
Use this command to enable or disable non-DFE mode on a specified port or on a range of ports, or to
display the configuration.
Active receiver DFE uses sophisticated algorithms to automatically adjust the receiver to compensate for
signal distortions.
If enabled, this command disables the active receiver DFE and instead uses a fixed receiver
equalization.
If the non-DFE enabled port is connected to a port that does not require fixed receiver equalization, CRC
errors may be detected on the port and the link may toggle.
By default, non-DFE mode is disabled, which means the automatic adjustment through DFE is activated.
If non-DFE is already enabled on the ports, enabling non-DFE has no effect. If a range of ports is
specified, some of which are already in the requested configuration, a notification is generated, and no
action is taken for those ports only. All other ports in the specified range are updated. Enabling or
disabling non-DFE is disruptive to traffic.
When used with the --show option, the command displays the following information for the specified
ports:
Port
The port index number.
Non-DFE Configured
Displays ON if non-DFE is enabled on the port.
Displays OFF if the feature is disabled (default).
Use the portCfgShow command to display the non-DFE configuration along with other port parameters.
NOTES
This command is applicable only on an 8 Gbps Condor3 port.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS
This command has the following operands:
slot/
Specifies the slot number to be configured on bladed systems.
port[-port]
Specifies a port or a port range, relative to the slot number on bladed systems.
This command does not support multiple port ranges.
--enable
Enables non-DFE on the specified ports.
